this sucker is tough. I fought him for 3 yrs but I've gained weight. it's an older one when bravestar was only offering the 14 oz or the 21 oz. this one is the 21 ounce. I had to replace two of the buttons. they are pictured. this thing will survive a nuclear apocalypse. lots and lots of life left. take note of the measurements it's a snug large on me.
